GAS-BURNER.

Application filed November 28, 1908.

To all whom it may concern:

Be it known that I, J Axis OSCAR SHoor, a citizen of the United States, residing at Winfield, in the county of Cowley and State of Kansas, have invented new and useful Improvements in Gras-Burners, of which the following is a specification. f

This invention relates to hydrocarbon burners, and has for an object to provide a burner adapted for use in connection with steam boiler furnaces and to provide means whereby the burner can be conveniently applied to the fire door of a furnace of ordinary construction.

A further object of this invention is to provide a burner so constructed whereby air and gas may be thoroughly mixed before being discharged to the ii're box of the furnace, and to provide means adapted for operation to mix any required amount of air or gas to be discharged to said burner and thus reduce its cost of operation to a minimum.

Other objects and advantages will be apparent as the nature of the invention is better disclosed, and it will be understood that certain changes may be resorted to without departing from the spirit of the invention.

In the drawing, forming a portion of the specication reference indicate similar parts in the several views, Figure 1 is a longitudinal secboiler furnace showing the application of the present burner thereto, Fig. 2 is a front view, Fig. 3 is a is a detail sectional view through the fuel feed Referring now more particularly to the drawing where is shown a steam boiler furnace 5 of ordinary construction which is provided with a hinged fire box door 6 for gainformed a passage for the reception of a mixing chamber 7 which is preferably of recarched top 8. The rear wall of the mixing chamber is provided with a plurality of mixed gases as is obvious. In the front wall of the mixing chamber is formed a passage ing its reduced end extending outwardly of the furnace as indicated.

of the furnace and adjacent to the front wall thereof, and this pipe is provided with a controlling valve 12 of any desired construction. The pipe 11 is connected by means of an elbow 13 to a vertical pipe 14 which carries at its upper end an elbow 15 for receiving a telescopic pipe 16, having a stationary outer section 17 and a slidable inner section 18. The outer section 18 is movable toward and away from the inlet end of said nozzle 10 and may thus be moved or disposed within said nozzle or which may be moved whereby its extreme outer end is in spaced relation to the outer end of the nozzle, thus regulating the amount of air fed to said nozzle, it will of course be understood that the intake end of the nozzle 10 is of a greater diameter than the diameter of the pipe and that air thus enters the nozzle through an annular space when thesection 18 is disposed partly within said nozzle. A horizontally disposed pipe 19 extends through the chamber adjacent to the upper end thereof, and through this pipe extends a smaller pipe 20, the outer end of which is tapped into the elbow 15 and is provided with a valve 21, as shown, the pipe 20' being thus used as a pilot burner, and the iiame of the burner when said burner is lighted is located directly above the perforations 9 formed in the rear wall of the mixing chamber.

It may be stated that when in use, the pilot burner is first lighted, and fuel is afterward permitted to enter' the mixing chamber through the nozzle 10 and may be lighted as it is discharged at the rear of the mixing chamber. The construction of the burner as herein set forth and described is extremely simple, may be applied to furnace doors of the hinged type whereby it may be conveniently cleaned when the door of a furnace is in an open position. l/Vhen the burner has been lighted it will of course be understood that the pilot burner is extinguished, and the pipe 19 which contains or through which is passed the pipe 2O may be closed in any suitable manner if desired.

Having thus described the invention what I claim is 1. In a device of the class described, the combination with a steam boiler furnace having a hinged fire door, of a mixing chamber carried by the fire door and having a plurality of perforations in one of its walls opening into the fire box of the furnace, an air and fuel receiving nozzle carried by the forations, anair and chamber, and an adjustable fuel discharge pipe located to discharge into said nozzle.

2. The combination with, a steam boiler furnace having a hinged re door, of a mixing chamber carried by the door and having a plurality of gas discharge perforations in its rear Wall opening into the re boX of the furnace, a pilot burner located abovethe per-y gas receiving nozz' carried by said chamber, and a gas supply pipe located adjacent to the said nozzle.

In testimony whereof I aHiX my signature in presence of two Witnesses.
